In this guide, FenSo explains standard mobile home interior door sizes, how to measure correctly, and what factors to consider when selecting a new door.
What Are Mobile Home Interior Doors?
Mobile home interior doors are designed specifically for manufactured and mobile homes. Because mobile homes are built with different structural requirements than conventional houses, their doors may have unique widths, heights, and thicknesses.
Many homeowners assume standard residential doors will fit their mobile homes, but this is not always the case. Understanding the correct dimensions can save time, money, and installation headaches.
Standard Mobile Home Interior Door Sizes
While dimensions can vary depending on the manufacturer and year of construction, the following sizes are among the most common.
Common Mobile Home Door Widths
| Door Width | Typical Application |
|---|---|
| 20 inches | Small closets |
| 22 inches | Utility rooms |
| 24 inches | Bathrooms and closets |
| 28 inches | Bathrooms |
| 30 inches | Bedrooms |
| 32 inches | Master bedrooms |
Common Mobile Home Door Heights
Most mobile home interior doors are available in:
- 72 inches
- 74 inches
- 76 inches
- 78 inches
- 80 inches
Older manufactured homes frequently use shorter door heights than modern residential homes.
Standard Mobile Home Interior Door Thickness
A standard mobile home interior door is typically:
1⅜ inches (35 mm) thick
Traditional residential interior doors are often:
1¾ inches (44 mm) thick
This difference may affect:
- Hinges
- Door knobs
- Latch systems
- Door frames
Before purchasing replacement hardware, always verify door thickness.
How to Measure a Mobile Home Interior Door
Accurate measurements are the key to a successful replacement.
Step 1: Measure Door Width
Measure horizontally across the door slab from edge to edge.
Take measurements at:
- Top
- Middle
- Bottom
Use the widest measurement.
Step 2: Measure Door Height
Measure from the bottom edge of the door to the top edge.
Avoid including trim or molding in your measurement.
Step 3: Measure Door Thickness
Measure the thickness of the door slab using a tape measure or caliper.
Step 4: Measure the Rough Opening
The rough opening is the framed opening inside the wall before trim is installed.
Knowing the rough opening size helps ensure the new door and frame will fit correctly.
